| Post Translational Modifications | Phosphorylation at Ser-27 by PKA.increases delayed rectifier potassium channel activity of the KCNQ1-KCNE1 complex through a macromolecular complex that includes PKA, PP1, and the targeting protein AKAP9. Ubiquitinated by NEDD4L.promotes internalization. The ubiquitinylated form is internalized through a clathrin-mediated endocytosis by interacting with AP2M1 and is recycled back to the cell membrane via RAB4A and RAB11A. Deubiquitinated by USP2.counteracts the NEDD4L-specific down-regulation of I(Ks) and restores the membrane localization. |
| Function | Potassium channel that plays an important role in a number of tissues, including heart, inner ear, stomach and colon. Associates with KCNE beta subunits that modulates current kinetics. Induces a voltage-dependent current by rapidly activating and slowly deactivating potassium-selective outward current. Promotes also a delayed voltage activated potassium current showing outward rectification characteristic. During beta-adrenergic receptor stimulation participates in cardiac repolarization by associating with KCNE1 to form the I(Ks) cardiac potassium current that increases the amplitude and slows down the activation kinetics of outward potassium current I(Ks). Muscarinic agonist oxotremorine-M strongly suppresses KCNQ1/KCNE1 current. When associated with KCNE3, forms the potassium channel that is important for cyclic AMP-stimulated intestinal secretion of chloride ions. This interaction with KCNE3 is reduced by 17beta-estradiol, resulting in the reduction of currents. During conditions of increased substrate load, maintains the driving force for proximal tubular and intestinal sodium ions absorption, gastric acid secretion, and cAMP-induced jejunal chloride ions secretion. Allows the provision of potassium ions to the luminal membrane of the secretory canaliculus in the resting state as well as during stimulated acid secretion. When associated with KCNE2, forms a heterooligomer complex leading to currents with an apparently instantaneous activation, a rapid deactivation process and a linear current-voltage relationship and decreases the amplitude of the outward current. When associated with KCNE4, inhibits voltage-gated potassium channel activity. When associated with KCNE5, this complex only conducts current upon strong and continued depolarization. Also forms a heterotetramer with KCNQ5.has a voltage-gated potassium channel activity. Binds with phosphatidylinositol 4,5-bisphosphate. KCNQ1-KCNE2 channel associates with Na(+)-coupled myo-inositol symporter in the apical membrane of choroid plexus epithelium and regulates the myo-inositol gradient between blood and cerebrospinal fluid with an impact on neuron excitability. Isoform 2: Non-functional alone but modulatory when coexpressed with the full-length isoform 1. |
